HTC seems to be preparing a hardware refresh for this year’s One X Android, giving the phone a slight processor bump. We’ve been hearing about this model as the One X+, which will apparently go with a new Tegra 3+ chip and raise the phone’s clock speed to 1.7GHz. Now some newly-leaked information has surfaced, supposedly right out of HTC itself, providing a little more data on the handset.

This info confirms what we’ve heard about a 1.7GHz quad-core SoC, though doesn’t go into any further detail on the silicon. It mentions that the phone will feature battery improvements over the first One X, though we’re not sure if that means better power management or just a larger battery. HTC may also provide some new color options not previously available on the One X.

Beyond just hardware tweaks, HTC also reportedly has some new software ready for the phone, including a new HTC Watch 2 app for video streaming, and ClearVoice for enhanced call quality.

Just as the original One X first came to our attention as codename Endeavor, this One X+ may have picked up the codename Endeavor C2 for itself. This leak mentions a launch on or before October 1; that’s consistent with the September 26 revealed by a T-Mobile roadmap.
